now I put the kext "BETA" 2.1.1 PS2 but same result, I really tried them all, but I can't give up now, I have to insist ......
From the vision of the ACPI origin do you have ideas ???? I have not found any ACPI folder with similar structure among the configurations found on the DELL network
I have read in some guides that removing _DSM methods is not good, so I didn't use that rename

 

This is the keyboard for brightness keys

Jake Lo thanks for the support, for the brightness adjustment I solved it with USB mouse-keyboard, inserting the receiver and from system preferences I set everything up and it works perfectly always .........
The touchpad is missing and it just doesn't want to be activated

What patches did you have on the DSDT?

Try removing it and just keeping the SSDT-xxx

Hello Jake Lo , this my folder OEM , touchpad no work ..............

I can only tell you that I have tried every possible solution, with DSDT, without DSDT and I have also tested various SSDT-I2C solutions found on the net, but nothing is wrong
